Target Reference Server
Rftools Overview
The rftools MCP server exposes rftools.io's RF and electronics calculators and simulation jobs to AI agents. It provides 255 calculators for tasks such as microstrip impedance, link budgets, filters, converter sizing, and antenna analysis, along with 13 server-side simulations. Calculators run locally without a key, while simulations use a free lane unless an API key is supplied; file-based inputs and some higher-capability modes require the key. Use it when an agent needs engineering calculations or RF simulation results through MCP.
Primary Use Cases for Rftools:
- Calculate microstrip impedance and transmission-line parameters
- Analyze RF cascades and satellite or terrestrial link budgets
- Simulate antenna behavior, FDTD lines, and S-parameter workflows
- Evaluate filter variation with Monte Carlo analysis
